Answer 1

Sure! Here’s a breakdown of the body systems involved in each scenario:

Scenario 13: Jerking away from a tack

• Nervous System: The reflex action is processed through the nervous system, where sensory neurons detect pain from stepping on the tack, and the spinal cord sends an immediate signal to the muscles to jerk away.
• Muscular System: The muscles in your leg contract to quickly pull your foot away from the tack, allowing you to avoid further injury.

Scenario 14: Drinking sugary soda and needing to use the restroom

• Digestive System: The sugary soda is processed by the digestive system, where it is broken down and absorbed into the bloodstream.
• Urinary System: The increased sugar content and fluid intake lead to the production of urine, prompting the need to urinate before the next class period.
